SILK-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,696, dated May 13,1890.

Application filed April 17,l 1888 Serial No. 270,964. (No model.)

To all whom it may concern:

Be it known that we, HENRY D. KLOTS and HARRY NIGH'JFINGALE, citizens ofthe United States, both residing at New York, in the county and State ofNew York, have invented certain new and useful Improvements in Silk-Vinding Machines, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itappertains to make and use the same, reference being had t-o theaccompanying drawing, forming part of this specification.

vOur invention relates to machines for transferring or winding silk orother fibrous material from swifts onto rotating winding spools orbobbins.

It is a great advantage in mill machinery to have the same compact inarrangement, so as to occupy the minimum of iioor-space. S0 important afeature is this that preference is invariably given the more compactforms.

The chief objects of our invention are to double the winding capacity ofthe silk-winders heretofore used without in any way increasing thetloor-space occupied thereby, and

to make certain parts of the machine perform double functions.

To the aforesaid purposes our invention, briefly stated, consists inwhat we term a double-deck winding-machine, having an upper swift and alower swift disposed subjacent thereto, with a suitably-driven windingspool or bobbin co-operating one with each of said swifts, each spoolacting to wind thereon the silk delivered by its co-operating swift, andin a stationary thread-guide and a traversing guide, each common tobot-h of said swifts, and a driving friction-drum common to both of saidspools for rotating the same.

The accompanying drawing is a vertical transverse sectional view of oursocalled double-deck winding-machine constructed in accordance with ourinvention.

Referring to the drawing, the machine frameworkcomprises a set ofthejvertically-arranged frames or uprights 1, preferably made ofcast-iron, and the side rails 2 2, which are secured to the sides of theframes 1, near the bases thereof, and run longitudinally of the machine.Upon the tops of the frames is se= curely set a table 3, extending thelength of the machine, and the stand 4 is fixed rigidly upon the table.The lower swifts 5 5 are correspondingly disposed at the lower part ofthe machine and turn idly in the half journal- 5 5 boxes formed in theupper ends of the swiftsupports 6 6, which have their lower ends boltedto the rails 2 2 and are inclined inwardly, so as to bring the swiftswithin the basal lines of the machine. The upper swifts 7 7 are arrangedsimilarly upon each side of the machine,'and are preferably sustained inoperative positions by the swift-supports 8 8, (like those described forthe lower swifts,) which are bolted to the st-and Ll. Ve have shown theupper and lower sets of swifts disposed in pairs, onedirectly above theother, with their axes in the same vertical plane. However, thisarrangement may be varied, if preferred, by setting the upper swiftsfarther in toward the center of the machine, so that they will justclear each other in their revolutions, or they may be placed fartherout; but the requirement always to be observed is that the upper andlower swifts shall be arranged in pairs, one substantially over theother. The brackets 9 9 are fixed to the sides of the machine andproject laterally therefrom at right angles, and serve to support therotatable friction drum shafts 10 10, which extend lengthwise themachine, and upon these shafts are keyed the friction drums or wheels 1111, which are rotated in opposite directions by means of the bevel-gears12 12, fixed at the ends of the shafts 10 10, gearing with thebevel-pinions 13 13, which are fast upon the respective ends of the mainshaft 14, mounted suitably at one end of the machine and provided withthe stepped belt-pulley 15, which may be driven in any desired manner.9o

Overhanging the friction-drum shafts are a set of spool-bearing arms 1616, which are rigidly attached, preferably, to the edges of table 3 andextend at right angles therefrom. These bearing-arms are each providedwith two suitable journal-bearings 17 17, made, preferably, open at thetop, so that the spool spindles 1S 18, upon which the spools 20 20 aremounted, may be readily dismounted in defi-ing and replacing the spools.Motion is given the spools by virtue of the spindlehubs 19 19 of thespool-spindles being in frictional contact with the peripheries of thefriction-drums 11 11 at corresponding points to the right and left ofthe high part of the drums, as clearly indicated in the drawing.

Upon the ripper sides of the brackets 9 9 are fixed the standards 21 21,having forked heads provided with anti-friction rolls 22 22, coming incontact with the under sides of the traverse-rails 23 23, which areprovided with ordinary thread-guide eyes 24 24, located at suitableintervals thereon, and preferably we employ one traversing guide for andin common with two spools, which are driven by one drum. At the ends ofthe brackets 9 9 are secured the vertical posts 25 25, through the eyesin the heads of which pass the stationary thread-guide bars 26 26, whichextend lengthwise the machine parallel with the traverse-rails.

We. have considered it unnecessary to describe or illustrate more indetail the driving mechanism for the spools and the construction of thetraversing means, since these features are Well known to those familiarwith textile machinery. However, for the more thorough understanding ofthe saine, reference maybe had to United States Patent No. 257,269,granted May 2, 1882, and Patent No. 373,486, granted November 22, 1887.

The drawing illustrates aV Winder having our invention duplicated uponeach of the opposite long sides thereof, as is usual in this class ofmachines. In the operation of the Winder the silk thread or filament 27runs from a lower swift 5 over a stationary threadguide bar 26, througha traversing guide 24, thence, preferably, to an inner rotating spoolor` bobbin 20, which serves to wind the same thereon from itsco-operating lower swift. The thread 28 passes from an upper swift 7,under the guide-bar 26, thence through a traversing guide 24E,preferably, to an outer spool 20, which acts to wind thereon the threadfrom its co-operating upper swift. For the sake of clearness the threads27 and 28 are shown as running quite an appreciable distance apart ontheir way through the traversing guides; but in actual operation theygenerally run in contact at these points. Of course it will be optionalin regard to emling the capacity of the Winder without in' creasing thefloor-space occupied thereby, our winder provides a set of overhead orupper swifts conveniently located both for ma nipulation and inspectionby the operative.

Having thus described our improvements in silk-winding machines, what weclaim as our invention, and desire to secure by Letters Patent, is-

1. In a silk-winding machine, the combination, with a pair ofoppositely-arranged swifts, a spindle carrying a rotating winding-spoolfor each of said swifts,rotating means for the spindles, and astationary thread-guide common to both of said swifts, of a traversingguide common to both of said swifts and imparting the requisite lateralmotion to the threads in building the load on the spools, substantiallyas described.

2. In a silk-winding machine, the combination, with a pair of oppositelyarranged swifts, such as 7 and 5, suitably mounted spool-spindles, suchas 18, arranged one for each swift and carrying a winding-on spool 20,and means for rotating such spindles, of a single traverse-guide, suolias 24, and a single stationary thread-guide, such as 26, thetraverse-guide and the thread-guide each acting in common with both ofsaid swifts and winding-on means, respectively, substantially as and forthe purpose set forth.

In testimony whereof we have hereunto set our hands and seals, this 6thday of April, 1888, in the presence of the two subscribing witnesses.
